Set during the early days of Augusto Pinochet's dictatorship, Chile '76 builds from quiet character study to gripping suspense thriller as it explores one woman's precarious flirtation with political engagement. Carmen (Aline Kuppenheim, A Fantastic Woman) leads a sheltered upper middle class existence. She heads to her summer house in the off-season to supervise it's renovation, while also performing local charitable works through her church. Her husband, children, and grandchildren come back and forth during the winter vacation, bringing reminders of the world beyond. When the family priest asks her to take care of an injured young man he has been sheltering in secret, Carmen is inadvertently drawn into the world of the Chilean political opposition and must face real-world threats she is unprepared to handle, with potentially disastrous consequences for her and her entire family.
